To all whom it may concern Be it known that I, FRANK l. Mornn, of Utica, in the county of Oneida and State of New York, have invented. certain new and useful Improvements in -Window-Screens; andl do hereby declare that the following is a full clear, and exact description thereof, which will enable others skilled in the art to which it appertains to malte and use the same, reference being had to the accompanying drawings, and to the reference numerals marked thereon, which form part of this specification.

The purpose of my inventionis to pro vide an improved window screen of the class wherein a part of the screen is a sash movably mounted in the main screen frame, so

that people within the house may have ready access through the window, as for reaching the outside blinds or obtaining a more unobstructed View.

My object is-to pr0vide a construction that is simple and durable and one that will insure at all times an easy operation of the movable sash.

Heretofore movable screen sashes have usually been slidingly mounted in the frame by placing the entire side edges of the sash in grooves or slideways. This method re.--

sulted in a large amount of surface in frictional contact and was not satisfactory as the sash was held too tight for easy move ment on account of slight variations in the size of the engaging parts or the angle of the window frame or screen or on account of the action of the weather upon the screen.

To provide 'a construction that will effectively overcome these difficulties is one object of my invention.

Other advantages of construction will ap-.- pear from the specification'and claims that follow.

a diagrammatic view on an enlarged scale showing the operation of the spring catch.

Referring to the drawings in a more particular description, the frame 10 is composed. of sides 11 connected by a top 12, central cross-piece 13, fixed bottom cross-piece 14- and a removable bottom cross-piece 15. To the outer side of the upper half of this frame is permanently secured the upper screen 16 of woven wire cloth or other suitable screen material, extending from side to si' e and from the top 12 to the central. crosspiece 13 and preferablyhaving a facing or inding strip 17 in the usual manner. The frame 10 is set into the window fame 18 from without and preferably sets up against the outer edge of the outer window sash stop 19 and may be secured in place by anv suitable means such as small angle brackets 2.0 fastened to the sides 1.1 of the frame and to the stop 19. r Upon the inner edge of each of the sides 1]. there is provided a groove 21 extending the entire length of the side into which pro ject and loosely lit the rounding pins 22 which project from the side edges of the sliding screen sash. 23. This sash is a rectangular frame consisting of top and bottom cross pieces 24 and 25 respectively and side pieces 26, having aflixed thereto on its inner surface a proper screen material 27 with the usual facing strip 28 covering the edges of the screen material. The sash 23 is of such width as to fit loosely between the sides 1]. of the main frame 10 and of such length as to close the lower part of the frame which is not provided with screen The pins 22 serve to hold the movable sash in the frame and allow it to be easily raised and lowered therein. The pins are of less diameter than the width of the groove 2]. and'their projecting length is less than the depth of the groove 21 1 prefer to use only two of these pins on each side of the sash. 'lihe widihof the sash: issuch that when one side is'against one'side piece 11 of the frame 10 the other side of the sash will not touch its adjacent side piece 11. It will'iiius' be seenthat the sash. cannot hind or sticlr in the frame and that there are only four contact points of the pins-22in the grooves ill and. that frictionat these tie-6 of ll ig 1. Fig. 7 a sidatonedge. fpoints'is reduced to a minimum bye-re o till its

sides 11 toward their outer siirface, of such height as to project beyond the outer edge of the sash in any position it may talre and so positioned relative to the erth of the movable sash as not to be in contact therewith but close enough to prevent insects from going through said space. This projection may conveniently be formed integral with the sides 11.

For convenience in asshmbling the screen and in order to be able to remove the sash from the frame readily, If form the iower end of the frame with a permanent bot- ;om cross-piece i land e removable bottom cross-piece 15. Ti lie permanent bottomj is rigidly secured to the sides 11 and isso located toward the outer surface of the frame and of such thickness as to allow the sash to he slid by it out of the frame when the bottom piece 15 is removed and the frame or at least its lower end withdrawn from the Window casing. The removable bottom. cross-piece is of such thickness as to prevent such removal of the sash as may be conveniently held in place by pins or tongues projecting from the ends of the bottom W 15 and fitting snugly into the. grooves 2i and by screws 31 passing through the tilted bottom 14 into the upper part of the bottom piece 15, as clearly appears in 9;, 3 and s.

A spring catch 32 upon the bottom crosspiece of the sash has e point 33 to engage a clip 34:: upon the central cross ber 13 when' the sash is raised, and a point 35 to engage a clip 36 upon the bottom of the frame when the sash is in its normal lower position.

What I claim as, new and desire to secure by Letters Patent l. The combination in a window screen of b rigid frame iormihg s closure of the entire window, frame and removable bodily therefrom consisting of top and bottom cross-pieces and two sides haying inwardly extending grooveson their inner edges, a screened movable sash normilly closing the lower part of said frame and loosely fitting between said frame sides, pins projecting from the side edges of said sash into said grooves and adapted to slidingly hold said sash between said frame sides, a central cross-piece out oi the path of said sash and a fixed screen over the upper part of said.

lower part of said frame and loosely fitting between said frame sides, dpins projecting from the side edges of sai sashinto said grooves and adapted to slidingly hold said,

sash between said frame sides, a central cross-piece out of the. path of said sash, a fixed screen over the upper part of said .jframe secured to said top and central cros -pieces and the sides and strips projecting from 'said frame sides beyond theouter edges of said sashand spaced therefrom.

3. The combination in'a window screen of a rigid frame forming a closure of the entire window frame and removable bodily therefrom consisting of s, top, a central and e fixed bottoin cross-piece and two sides having inwardly extending grooves on their inner edges, a s eened movable sash normally closing the 1 wer port of said frame and loosely fittingi'between said frame sides, pins projecting from the side edges of said sash into said grooves and adapted to slidingly hold said sash between said frame sides, a fixed screen over the upper pa of said frame, said central and'fixed hot in crosspieces being out of the path of said mov able sash, and a removable bottom crosspiece closing the lower end of said slots.

In witness whereof I have allixed my signature, in the presence of two Witnesses, this 21st day of June 1911.
